Question 1

Is this Skylake ready? i.e. Will it take advantage of Skylake's power saving features?

Accepted Answer

Generally speaking power supplies are built to be universal.  A power supply only puts out the power that is needed to run the system.  The rating (80 plus rating) tells you how much extra power it needs from the wall to power your computer.  For example seeing how this is Gold Rated to produce 100 watts for the computer it needs an extra 10% from the wall (that is what it means by 90% efficient).  So if you processor has a power saving feature it will be useful and save power.  So when getting a power supply the 80 plus rating is the most important thing for saving power.  If you have any questions feel free to ask.  There is no such thing (aside from higher end ones in servers for exampel) as a smart power supply.
